Oxidative hydrolysis and acid-catalyzed rearrangement of steroidal isoxazolidines
(Elsevier, 1991)
Treatment of steroidal isoxazolidines 3a, 3b and 5b with N-methylhydroxylamine hydrochloride in boiling ethanol-pyridine (1:1) solution results in elimination of the CH3NH2fragment, affording products of oxidative hydrolysis ...
The influence of OH- chemisorption on the catalytic properties of gold single crystal surfaces for oxygen reduction in alkaline solutions
(Elsevier, 1996)
Oxygen reduction on gold single crystal electrodes of various orientations, Au(hkl), in 0.1 M NaOH was studied by rotating disk electrode and rotating disk ring electrode techniques, with a goal to correlate the physical ...
Synthesis and evaluation of several cathechol bioisosteres as potential dopamine receptor ligands
(Elsevier, 1991)
Derivatives of benzimidazole (I), benzimidazolone (II), benzimidazolethione (III), 2,3-dihydroxyquinoxaline (IV) and the noncyclic acetamide (V) and t rifluoroacetamide (VI) of the corresponding 1,2-pheny-lenediamiane were ...
The role of surface defects in HOPG on the electrochemical and physical deposition of Ag / Uloga površinskih defekata na HOPG-u u elektrohemijskoj I fizičkoj depoziciji Ag
(Belgrade : Serbian Chemical Society, 1999)
The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by ...
A New Approach to Metal Electrodeposition at a Periodically Change Rate. Part I. The Reversing Overpotential Method
(Elsevier, 1999)
A method of increasing the apparent deposition exchange current density value in reversing overpotential (RO) copper electrodeposition is described. In pulsating overpotential (PO) metal electrodeposition, the current ...
Scanning tunnelling microscopy of the nucleation and growth of sputter-deposited Cr on graphite
(Elsevier, 1995)
In this paper, we present a study of the nucleation and growth stages of sputter-deposited Cr thin films on highly oriented pyrolytic graphite (HOPG) substrates using scanning tunnelling microscopy (STM) in air. Freshly ...
X-ray crystal structure of 10β-hydroxy-4β,5β-epoxyestr-1-en3,17-dione and antitumor activity of its congeners
(MDPI, 1999)
Based on the biological properties of epoxyquinols from natural sources, the title compound was synthesised as a potential antitumor agent. Its molecular structure was partially confirmed by NMR studies. The detailed ...
RuO2–TiO2 coated titanium anodes obtained by the sol–gel procedure and their electrochemical behaviour in the chlorine evolution reaction
(Elsevier, 1999)
TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis
at elevated temperature. The Ti supported coatings were obtained by the sol–gel method using a sol mixture in ...
